Reasons for slow growth of dogs:

1. Insufficient nutrition leads to insufficient nutrients to supplement the growth of dogs, resulting in slow growth.

2. Calcium deficiency, vitamin deficiency, etc. are all causes of slow development of dogs.

3. The digestive function of the gastrointestinal tract is poor. The problem caused is that even if a lot of food is eaten, nutrients cannot be absorbed, resulting in slow growth.

4. Dogs have diseases that cause slow growth and hinder the dog’s nutrient absorption.

5. Innate physical constitution, caused by inheriting the gene for slow growth.
